I'm currently running 18 strips (ten 56 diode strips and eight 40 diode strips) at 13 amps total current and the channel they are mounted on does not get very hot at all, I can rest my hands on it with no discomfort. By my calculations the 56 diode strips should be pulling 800+ mA, so I think one amp is doable with no heatsink. If you want to sink them, 3/4" architectural aluminum channel is available at most hardware stores for about ten bucks per 8 feet.Do you feel they need heatsinking at 1 amp? Looking at possibly grabbing a four-pack of the 56-diode strips from eBay (in 4000k - $20), but I'd like to work out the cooling requirements before I pull the trigger.
The numbers below are from Bridgelux EBgen1 strips (nom. and max. current) but I could imagine that the numbers of the Ac. strips are comparable.Has anyone taken any temp measurements on a bare strip, no heatsink, no aluminum? The application I have in mind would ideally run them bare. I see the eBay seller says no heatsink is required at 1 amp, but it's always good to check on real-world results.
